The StarGuider guiding tool is a good alternative to traditional guidings. The 50 mm objective lens f / 3.2 allows you to obtain bright, wide-angle images and allows you to photograph images with a long exposure time with telescopes with up to 1500 mm focal lengths, also for autoguiders with small chipset sizes. The telescope is attached either as a separate finder or even in place of your finder (Vixen / SkyWatcher standard foot). This is a much cheaper method than buying a separate guidewire together with the assembly or off-axis guider.
